Acoustics is the study of sound, noise, and vibration. Understanding the acoustical performance of your product is important because different types of devices have different thresholds for acceptable amounts of acoustic noise. Acoustic testing services assess how your product will perform in real-world conditions, and whether or not further revisions should be made to reduce noise. Acoustical testing helps product manufacturers from various industries determine these values.
NVH, which stands for Noise, Vibration, and Harshness, is the study of the noise and modification vibration characteristics of vehicles and is basically a measure of how much unpleasant aural and tactile feedback the vehicles deliver as you drive. NVH testing enables early recognition of NVH phenomena, which can then be avoided early during the development stage of the powertrain. This later makes driving in the production vehicle more comfortable and serves to avoid complaints and a loss of image.
Acoustic Testing is performed to determine if the material can resist the specified Acoustic environment. It must resist this environment without degradation of its functional performance and/or structural integrity. Acoustic Testing or Acoustic Emission Testing is the measurement of sound emissions radiating from the equipment under test. In other words, how loud is the equipment?
